steel baseplate design
(OP)
I AM TRYING TO DESIGN A STEEL BASE PLATE FOR A COLUMN CONNECTION BUT I AM HAVING TROUBLE FINDING A DESIGN GUIDE. CAN ANYONE GIVE ME THE TYPES OF THINGS TO CHECK FOR AND FAILURE MECHANISM AND A POSSIBLY A DESIGN GUIDE TO FOLLOW.
PU= 10 KIPS
VU= 4.5 KIPS
MU= 53 KIP-FT
4 ANCHOR BOLTS
4000 PSI CONCRETE
PROPOSED 16X16 BASEPLATE 1/2" THICK
POSSIBLY AN HSS 10"X10"X3/8"
ALL HELP IS APPRECIATED I AM A RECENT GRADUATE AND NORMALLY I WOULD ASK MY LEAD ENGINEER BUT HE IS ON VACATION AND THE OTHER LEAD ENGINEER IS NOT THE TYPE ONE ASKS QUESTIONS TO.

It has several useful examples.
If you or someone in your office is a member of AISC, you can download it for free from www.AISC.org

Also, I was not able to get a copy of rev. two and was told it was not available on the site anymore due to some errors in the publication.
The person I spoke with was very knowledgable on the subject and not only provided me with the above information but was also able to answer the question I was planning on using the guide for.

DOES ANYONE HAVE ANY EXAMPLES I CAN FOLLOW WITHOUT INFRINGING ON COPYRIGHTS?

Better go by the design example when youfind it as there is a prying action that is incorporated into those equations that are not included in the transformed area/concrete beam method you speak of. BE CAREFUL HERE!!!

As for the lead engineer that doesn't want to mentor graduates, I think they should have a good hard look at themselves and ask themselves why they are a "structural engineer" for, there are no "i's" in "team". I found myself in the same postion when I first graduated and it was incredibly frustrating, almost to the point where I thought I was absolutely wasting my time and felt my development lagged a bit because of it.

Be sure to check the anchor bolts (including the concrete failure modes) for combined tension and shear if you do that.
RE: steel baseplate design
what im saying it is standard practice in my company to check the actual shear against 2 bolts only not 4.. this is due to oversized holes.. baseplate are always oversized for erection purposes..
we dont weld washers we use shear lug if shear is too big..
RE: steel baseplate design
RE: steel baseplate design
By welding washers to the baseplate, we can enhance the concrete shear capacity which may be critical. Also, it enhances the bolt group shear capacity with regard to the steel failure.

Now i ahve another question though how do you modify these calcs if you have biaxial bending shear and moment.
